Nested table using apex:pageBlockTable, possible?

Hi, is it possible to create nested table on apex page using pageBlockTable or other tags?

I got an erreor: Save error: Object type not accessible. Please check permissions and make sure the object is not in development mode: SOQL statements cannot query aggregate relationships more than 1 level away from the root entity object. RequestAsPDF.page.

Using <apex:column breakbefore> and a controller extention could fill the child table content in a new row.

Elsewhere in your controller, call the necessary recursive queries to get all the data you need to populate this structure.

Finally, in your VF page, you can nest the tags recursively, as what you were originally trying to do; the syntax will be slightly different, obviously, because now you have a class that wraps the values in a way that can be fed to the pageBlockTable tag.
